I have a variable $my_arr whose var_dump($my_arr) value is
array(3) { [0]=> object(stdClass)#6 (9) { ["prod_index"]=> string(1) "1" ["prod_code"]=> string(4) "amp1" ["prod_name"]=> string(11) "Amplifier A" ["prod_price"]=> string(6) "100.00" ["frequency"]=> string(1) "2" ["gain"]=> string(1) "2" ["gain_variation"]=> string(3) "0.2" ["noise"]=> string(1) "2" ["power"]=> string(2) "10" } [1]=> object(stdClass)#7 (9) { ["prod_index"]=> string(1) "3" ["prod_code"]=> string(4) "amp1" ["prod_name"]=> string(13) "Amplifire1.33" ["prod_price"]=> string(6) "133.00" ["frequency"]=> string(4) "2.12" ["gain"]=> string(1) "2" ["gain_variation"]=> string(3) "0.2" ["noise"]=> string(1) "2" ["power"]=> string(2) "10" } [2]=> object(stdClass)#8 (9) { ["prod_index"]=> string(1) "4" ["prod_code"]=> string(4) "amp1" ["prod_name"]=> string(13) "Amplifier1.45" ["prod_price"]=> string(6) "150.00" ["frequency"]=> string(4) "2.99" ["gain"]=> string(1) "2" ["gain_variation"]=> string(3) "0.2" ["noise"]=> string(1) "2" ["power"]=> string(2) "10" } }
In smarty I tried
{foreach name = fe1 item = k from = arr}
{$k->prod_index}
{/foreach}
But it is not showing any result .
Assuming you're already assigning the array to smarty like:
$smarty->assign( "arr", $my_arr );
You need to use the "." syntax, like:
{foreach name = fe1 item = k from = arr}
{$k.prod_index}
{/foreach}

guys i have 4 table uhd_voucher_menu, uhd_menu, uhd_voucher_variant_menu, uhd_variant_menu
which uhd_voucher_menu and uhd_menu is connected by menu_id, than uhd_voucher_variant_menu and uhd_voucher_menu is connected by voucher_menu_id and the last, uhd_variant_menu and voucher_variant_menu is connected by variant_menu_id
this is my code how i get the data :
$this->db->select("uhd_voucher_menu.voucher_id,uhd_menu.menu_name,uhd_voucher_menu.qty,uhd_variant_menu.variant_name,uhd_voucher_menu.voucher_menu_id");
$this->db->from("uhd_voucher_menu");
$this->db->join("uhd_menu","uhd_menu.menu_id = uhd_voucher_menu.menu_id");
$this->db->join("uhd_voucher_variant_menu","uhd_voucher_variant_menu.voucher_menu_id = uhd_voucher_menu.voucher_menu_id","left");
$this->db->join("uhd_variant_menu","uhd_variant_menu.variant_menu_id = uhd_voucher_variant_menu.variant_menu_id","left");
$this->db->where("voucher_id",$data["voucher"]["voucher_id"]);
$this->db->where("uhd_menu.restaurant_id",$restaurant_id);
$res = $this->db->get()->result_array();
from that active recored will be return to this data :
[0]=>
array(5) {
["voucher_id"]=>
string(1) "1"
["menu_name"]=>
string(13) "Golden Salmon"
["qty"]=>
string(1) "2"
["variant_name"]=>
string(5) "Spicy"
["voucher_menu_id"]=>
string(1) "3"
}
[1]=>
array(5) {
["voucher_id"]=>
string(1) "1"
["menu_name"]=>
string(13) "Golden Salmon"
["qty"]=>
string(1) "2"
["variant_name"]=>
string(6) "Medium"
["voucher_menu_id"]=>
string(1) "3"
}
[2]=>

}

["menu_name"]=>
string(13) "Golden Salmon"
["qty"]=>
string(1) "1"
["variant_name"]=>
string(6) "Medium"
["voucher_menu_id"]=>

}
[4]=>
array(5) {
["voucher_id"]=>
string(1) "1"
["menu_name"]=>
string(14) "Red Crown Crab"
["qty"]=>
string(1) "2"
["variant_name"]=>

["voucher_menu_id"]=>
string(1) "1"
}
[5]=>
array(5) {
["voucher_id"]=>

string(8) "Omellete"
["qty"]=>
string(1) "3"
["variant_name"]=>
NULL
["voucher_menu_id"]=>
string(1) "2"
}
as you see the golden_salmon with same voucher_menu_id is return twice
i want if the voucher_menu_id is same, so from this data :
[0]=>
array(5) {
["voucher_id"]=>
string(1) "1"
["menu_name"]=>
string(13) "Golden Salmon"
["qty"]=>
string(1) "2"
["variant_name"]=>
string(5) "Spicy"
["voucher_menu_id"]=>
string(1) "3"
}
[1]=>
array(5) {
["voucher_id"]=>
string(1) "1"
["menu_name"]=>
string(13) "Golden Salmon"
["qty"]=>
string(1) "2"
["variant_name"]=>
string(6) "Medium"
["voucher_menu_id"]=>
string(1) "3"
}
i want that data return to become this :
[0]=>
array(5) {
["voucher_id"]=>
string(1) "1"
["menu_name"]=>
string(13) "Golden Salmon"
["qty"]=>
string(1) "2"
["variant_name"]=>
array(2){
[1]=>
string(5) "Spicy"
[2]=>
string(6) "Medium"
}
["voucher_menu_id"]=>
string(1) "3"
}
same as the other golden_salmon with same voucher_menu_id 4
i want the variant_name is become array so the if data with same voucher_menu_id will not call twice
guys can you help me how to execute the data as i want?
thank you (:
You have to use group by, I slightly modified you query:
$this->db->select("uhd_voucher_menu.voucher_id,uhd_menu.menu_name,uhd_voucher_menu.qty,GROUP_CONCAT(uhd_variant_menu.variant_name SEPARATOR ',') AS variants,uhd_voucher_menu.voucher_menu_id");
$this->db->from("uhd_voucher_menu");
$this->db->join("uhd_menu","uhd_menu.menu_id = uhd_voucher_menu.menu_id");
$this->db->join("uhd_voucher_variant_menu","uhd_voucher_variant_menu.voucher_menu_id = uhd_voucher_menu.voucher_menu_id","left");
$this->db->join("uhd_variant_menu","uhd_variant_menu.variant_menu_id = uhd_voucher_variant_menu.variant_menu_id","left");
$this->db->where("voucher_id",$data["voucher"]["voucher_id"]);
$this->db->where("uhd_menu.restaurant_id",$restaurant_id);
$this->db->group_by("uhd_voucher_menu.voucher_id");
$res = $this->db->get()->result_array();
we can convert the comma seperated values to array after query output.
Try and post the result...
I am having a hard time extracting a value from the following JSON object
array(3) { [0]=> object(stdClass)#1 (11) { ["Group"]=> string(2) "18" ["GroupName"]=> string(8) "Wireline" ["Region"]=> string(2) "15" ["RegionName"]=> string(8) "Atlantic" ["Province"]=> string(1) "1" ["ProvinceName"]=> string(13) "New Brunswick" ["City"]=> string(2) "11" ["CityName"]=> string(10) "Campbelton" ["Site"]=> string(2) "37" ["SiteName"]=> string(16) "Campbellton PNCT" ["Year"]=> string(4) "2016" }

I am trying to extract each item in a foreach loop within PHP Above is the var_dump of the $data[0] JSON object it demonstrates what the Array item looks like.
My foreach is the following
$data = json_decode($_POST["submitdata"]);
$Forecasts = $data[0];
foreach($Forecasts as $Forecast){
echo($Forecast->PlatformID);}
but it returns nothing as a result. Can someone explain to me how to get this from the second Array in the object?
simply place the Index of the inner array along with the object as shown below. This will check for the sub item for the PlatformID and return it to the screen.
foreach($Forecasts as $Forecast){
echo($Forecast[1]->PlatformID);}
I want get all rows of ref table : ciudad
public function actionGetCiudades(){
$model = ciudad::model()->findAll();
$lCiudades = array();
$i=0;
$dataReader = Yii::app()->db->createCommand( 'SELECT * FROM ciudad' )->query();
foreach( $dataReader as $row ) {
$ciudad = new ciudad;
echo $row->ciudadid.":".$row->estadoid.":".$row->ciudaddsc.":".$row->activo;
echo "<br/";
unset( $ciudad );
}
Unfortunately, output is :
:::
But I have 700+ rows in my table.
What's wrong???
UPDATE :
var_dump($dataReader) -->

Use queryAll() instead of query(). query() adds limit 1 to the sql query and gets only first row matching criteria.
As the Question title is generic let me post a generic answer to the question.
i am using Yii 2.
to get All rows from a table without applying any where class here is how you will get.
$dbusers = New Users;
$users = $dbusers->find()->all();
Your model should look like this.
namespace app\models;
use Yii;
use yii\db\ActiveRecord;
class Users extends ActiveRecord
{
public function rules()
{
return [
[['name', 'id','email','type'], 'required'],
['id', 'numeric'],
];
}
}
Final Code :
public function actionGetCiudades(){
$lCiudades = array();
$dataReader = Yii::app()->db->createCommand( 'SELECT * FROM ciudad' )->queryAll();
foreach( $dataReader as $row ) {
$ciudad->ciudadid = $row['ciudadid'];
$ciudad->estadoid = $row['estadoid'];
$ciudad->ciudaddsc = $row['ciudaddsc'];
$ciudad->activo = $row['activo'];
array_push($lCiudades, $ciudad);
unset( $ciudad );
}
$json = json_encode($lCiudades);
echo $json;
}
I thought to access the value of '1' here, I would need to the following
$data['category'][0];
["category"]=> array(1) { [0]=> string(1) "1" }
But it doesn't return anything. How would I access the string(1) section to get the value 1?
Here is the full var dump of the variable $data array

To access that data you have to use $data['revision_post']['category'][0] because category array is in revision_post array.
The value of $data['category'][0] is an array. So you would access like this:
$data['category'][0] = array('1');
echo $data['category'][0][0];
Try it for yourself by copying and pasting here http://writecodeonline.com/php/
array(1) {

Please help how do get only nid value in new variable.
get via
